This is a minecraft map where i have creator a game kind of like flappy bird i used the /setblock command and the /clone and when i was doing it i learned you can testfor/setblock different types of repeaters/comparators i found a bug where its /setblock ~ ~ ~ minecraft:unpowered_comparator 8 and it was a powered comparator when it says unpowered comparator so that is something notch had fix in 14w11b
For me to make this map i had to make blocks that you dont touch, no effect, and a block that is you
bedrock=you
diamondblock=goal
granite=bad
grass=bad
I Hope you enjoy and 1 more thing
